[0002] In the bar processing industry, as a key equipment, the bar feeder undertakes the important task of accurately and stably transporting bars from the storage area to the processing station. At present, the flip-type loading mechanism is widely used in small and medium-sized bar processing enterprises because of its simple structure, low cost and ability to adapt to bars of different shapes and sizes. However, in actual applications, the stability problems of the existing flip-type loading mechanism are prominent, specifically as follows: obvious shaking during flipping, causing the bars to collide and rub against each other, resulting in surface damage, accelerating the wear of the feeder components, and reducing the equipment life; inaccurate bar dropping position: it is difficult to ensure the position accuracy of the flipping shaking and the conveying track and the flipping structure, and when the bar drops, it cannot accurately fall into the predetermined position, easily causing jamming and stacking problems, requiring frequent manual intervention, reducing production efficiency, increasing labor intensity and cost, and may also affect the feeding and accuracy of the processing equipment, resulting in product quality problems.

Detailed implementation manners

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] As Figure 1 and Figure 2 shown, a bar feeder includes: a frame 1, and an installation platform is formed at the top of the frame 1 for installing components. Installation plates 2 are provided at both ends of the installation platform. A discharge hole is formed on the first installation plate 2, and two groups of side-by-side and oppositely arranged limit fixing seat groups 3 are provided on the second installation plate 2. As Figure 12 shown, the limit fixing seat group 3 includes an ejector rod 31. The ejector rod 31 is arranged on the installation plate 2 through a connecting seat, and the relative position with the connecting seat can be adjusted to change the action range of the ejector rod 31.

[0033] At least two groups of slide seat groups 4 are provided on the installation platform. In this embodiment, the number of the slide seat groups 4 is two, and they are arranged close to the two installation plates 2.

[0034] As Figure 3 and Figure 4As shown, the slide block group 4 includes a slide block support base 41 which is fixedly arranged on the installation platform, and a slide block side plate 42 which is arranged at the top and moves back and forth longitudinally through a first driving member. Specifically, two slide block limit blocks 44 are fixedly arranged at the top of the slide block support base 41, and are arranged near both ends of the slide block support base 41, and a slide block spindle 45 connected to both of them is arranged between the two. Two sliders 46 are slidably arranged on the slide block spindle 45, and the slide block side plate 42 is fixedly connected to the slider 46 and can slide along the slide block spindle 45 therewith.

[0035] Among them, the number of the slide block side plates 42 is two, and they are respectively fixedly connected to both sides of the slider 46. The first slide block side plate 42 is connected to the first driving member through a fixing block 47. The first driving member is a cylinder 15 which is arranged on the installation platform and can drive components such as the slider 46 to move back and forth on the slide block spindle 45.

[0036] A stock supporting plate support base 43 is arranged on the second slide block side plate 42. The stock supporting plate support base 43 rises and falls as the slide block side plate 42 moves. A stock supporting plate 6 is arranged at its top, and when the stock supporting plate support base 43 moves to the highest position, the stock supporting plate 6 is directly opposite to the discharge hole. The stock supporting plate 6 is V-shaped and is used for placing the bar stock. When it moves to be directly opposite to the discharge hole, the bar stock can be discharged from the discharge hole. Specifically, a vertical slot is opened on the second slide block side plate 42, and a first bearing 48 is arranged in the slot. The first bearing 48 is connected to the bottom of the stock supporting plate support base 43 through a connecting shaft, and a second bearing 49 is arranged on the connecting shaft on the side of the stock supporting plate support base 43 away from the slide block side plate 43. The second bearing 49 corresponds to an adjusting block 410 fixedly arranged on the slide block support base 41, and the side of the adjusting block 410 cooperating with the second bearing 49 is set as an inclined surface. When the slide block side plate 42 moves along the slide block spindle 45, the second bearing 49 will move from the lowest position of the adjusting block 410 to the highest position. During this process, the first bearing 48 rises to the highest position in the slot, driving the stock supporting plate support base 43 to move to the highest position. This moving process makes the stock supporting plate 6 move from the lower left to the upper right position, that is, from the bar stock feeding place to the discharging place, completing the translation feeding process.

[0037] Furthermore, as Figure 5 shown, another vertical slot is opened on the stock supporting plate support base 43, and a third bearing connected to the second slide block side plate 42 is fitted in the slot to maintain the stability of the movement of the stock supporting plate support base 43.

[0038] In addition, a limit fixing block 411 is provided on the second slide plate side 42 on one side of the stock supporting plate seat 43. A spring 412 is connected to the limit fixing block 411, and the other end of the spring 412 is connected to the stock supporting plate seat 43, which is used to keep the stock supporting plate seat 43 at the lowest end. When the slide plate side 42 moves from the lower left end to the upper right end, the spring 412 will be stretched, so that the slide plate side 42 has a driving force to return, ensuring that the slide plate side 42 accurately returns to its position.

[0039] As Figure 7 and Figure 8 shown, a base 5 is fixedly connected to the top of the slide plate side 42. A sliding block 7 driven by a second driving member to move back and forth horizontally is provided on the base 5. A feeding seat 8 that moves synchronously therewith is fixedly connected to the sliding block 7. A pushing plate 9 corresponding to the stock supporting plate 6 is provided at the first end of the feeding seat 8, and a feeding fixing seat 10 is provided at the second end. The pushing plate 9 can push out the bar stock on the stock supporting plate 6. A hole is opened in the middle of the feeding fixing seat 10, and a rear end shaft 11 that can move relative to the feeding fixing seat 10 is provided in the hole.

[0040] Preferably, a vertical plate is provided at one edge of the base 5, a slide rail is provided on the vertical plate, and at the same time, a synchronous belt 73 surrounding the vertical plate is provided on the base 5, and the synchronous belt 73 is driven by a second driving member provided on the base 5 to move. As Figure 9 shown, a synchronous belt fixing plate 71 is provided on the first side of the sliding block 7, and a synchronous belt sliding plate 72 is fixedly connected to the second side. The synchronous belt fixing plate 71 fixes the sliding block 7 on the synchronous belt 73, so that it moves with the synchronous belt 73. The synchronous belt sliding plate 72 is slidably matched with the slide rail provided on the base 5 to improve the stability of the movement of the sliding block 7. The second driving member is a motor 16, which is provided below the base 5 and drives the synchronous belt 73 to move through a transmission wheel.

[0041] As Figure 9 and Figure 10 shown, a pushing rod 12 is provided at the first end of the rear end shaft 11, and the second end extends into a rear end fixing seat 13 fixedly connected to the second mounting plate 2 and located between two groups of limit fixing seat groups 3. The rear end shaft 11 can be connected to the feeding fixing seat 10 and disconnected from the rear end fixing seat 13, and move synchronously with the feeding fixing seat 10; or it can be disconnected from the feeding fixing seat 10 and connected to the rear end fixing seat 13. At this time, the rear end shaft 11 is fixed on the rear end fixing seat 13, and the feeding fixing seat 10 moves independently.

[0042] Specifically, as Figure 11As shown, a longitudinal installation through-hole corresponding to the ejector rod 31 is provided at the second end of the rear-end shaft 11. An active pin 14 is slidably arranged in the installation through-hole, and the active pin 14 can connect the feeding fixing seat 10 or the rear-end fixing seat 13 and the rear-end shaft 11 into one body. Since the base 5 can move with the slide seat side plate 42, the rear-end shaft 11, the feeding fixing seat 10 and the rear-end fixing seat 13 can move between the two groups of limit fixing seat groups 3. When each component moves to cooperate with the first limit fixing seat group 3, the ejector rod 31 pushes the active pin 14 to move so that the rear-end shaft 11 and the feeding fixing seat 10 are connected into one body. When each component moves to cooperate with the second limit fixing seat group 3, the ejector rod pushes the active pin 14 to move so that the rear-end shaft 11 and the rear-end fixing seat 13 are connected into one body.

[0043] In this embodiment, the rear-end shaft 11 is circular. The feeding fixing seat 10 and the rear-end fixing seat 13 both have extending parts extending towards each other. The two extending parts are located on both sides of the rear-end shaft 11. The installation through-hole penetrates the rear-end shaft 11 and the two extending parts. By moving the active pin 14, the connection relationship between the rear-end shaft 11 and the two extending parts can be changed, realizing the connection and disconnection between the rear-end shaft 11, the feeding fixing seat 10 and the rear-end fixing seat 13. More specifically, both the feeding fixing seat 10 and the rear-end fixing seat 13 are in an L-shaped structure, and the two are combined to form a rectangular column structure.

[0044] Furthermore, a more-direction rocker 17 perpendicular to the active pin 14 is arranged on the active pin 14. The more-direction rocker 17 extends into a sliding groove opened at the second end of the rear-end shaft 11, which can prevent the active pin 14 from detaching from the rear-end shaft 11 and improve the structural stability.

[0045] As Figure 6 shown, a shock-absorbing block support seat 61 is arranged on the base 5. A plurality of shock-absorbing blocks 62 are arranged on the shock-absorbing block support seat 61. The shock-absorbing blocks 62 act on the bottom of the material supporting plate 6, which can improve the stability of the lifting of the material supporting plate 6 and also reduce the vibration when the material supporting plate 6 is lifted. The shock-absorbing block support seat 61 is located between the two groups of slide seat groups 4 and is provided with a vertical partition to isolate the pushing rod 12 and the material supporting plate 6.

[0046] Working process: The stock supporting plate 6 is in the initial position (lower left), and the bar stock can be placed on the stock supporting plate 6. Then, the air cylinder 15 works, driving the slide seat side plate 42 to move longitudinally. While the stock supporting plate support seat 43 moves longitudinally along with the slide seat side plate 42, it is lifted by the inclined surface of the adjusting plate 410 until it moves to the loading position (upper right). At this time, the rear end shaft 11 just moves to the second limit fixing seat group 3, and under the action of the ejector rod 31 of the second limit fixing seat group 3, the movable pin 14 is pushed to move, so that the rear end shaft 11 is connected to the rear end fixing seat 14; the motor 16 is started, and drives the sliding block 7, the feeding seat 8 and the pushing plate 9 to move horizontally through the synchronous belt 73. The pushing plate 9 pushes the bar stock on the stock supporting plate 6 to move to realize loading. After completion, the structures such as the feeding seat 8 move back horizontally under the drive of the motor 16. Then, the structures such as the sliding side plate 42 move back longitudinally under the drive of the air cylinder 15. At this time, the rear end shaft 11 just moves to the first limit fixing seat group 3, and under the action of the ejector rod 31 of the first limit fixing seat group 3, the movable pin 14 is pushed to move, so that the rear end shaft 11 is connected to the feeding fixing seat 10. The motor 16 works, driving the structures such as the feeding seat 8, the feeding fixing seat 10, the rear end shaft 11 and the pushing rod 12 to move horizontally, so that the pushing rod 12 pushes the bar stock just loaded into the processing equipment to complete pushing, and then returns. After returning, the above steps are cycled again.

[0047] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
